Cons

Con

Some programming experience is required

While the courses cover the very basics of Python, basic understanding of programming is needed to start learning from Google's Python class.

Con

It's Python

If you do not know Python or are not interested in coding or learning it, this is wholly unsuited for you. That's cool - it takes all kinds, and there are good alternatives available for you.

Con

Not primarily intended as an automation app

Pythonista is a general programming app; it can do automation, and do it well, but automation is not the primary focus of the app or it's users, and so it takes some digging to find the bits you need related to automation. I see this as a plus for the app in and of itself, but many will find an app that is focused on automation to be more useful for their needs.
